In my opinion, health is not six pack ABS or muscles.
It's how's your brain working, how's your mood, how's your gut, how's your skin, how's your energy levels. Are you fun to be around? It's a holistic conception, and studies consistently show that veganism and vegetarianism associated with higher rates of strokes, higher rates of depression, higher rates of infertility, sperm count declines, hormonal issues, so on and so forth.
